气相多环芳烃的吸附净化技术研究进展

Research progress on adsorption purification technology of gaseous polycyclic aromatic hydrocarbons

  • 摘要: 多环芳烃(PAHs)是近年来在大气污染问题中逐渐受到关注的一类污染物,不仅其自身严重威胁着人体健康,还可作为低挥发性物质促进二次颗粒物的生长.世界多国开始不断通过各种技术手段对废气中PAHs的排放进行控制,PHAs已成为大气环境领域共同关注的热点问题.吸附法是最具潜力且已被工业应用认可的一类PAHs控制净化关键技术,吸附剂对PAHs的吸、脱附性能是其中的关键.目前国内外学者无论是基于传统碳类吸附剂,还是新型的介孔吸附剂,都针对此类特殊低挥发性气体的吸附相平衡、动力学以及脱附特性做了相关研究,探悉了获取PAHs吸脱附最优平衡的关键因素以及最适吸附剂.本文针对这些结果及相关应用进行了综述,对比分析了介孔吸附剂较传统吸附剂在PAHs吸脱附特性上呈现的优势,旨在为PAHs及其他低挥发性气体吸附净化的相关工作提供有效参考.

     

    Abstract: Polycyclic aromatic hydrocarbons (PAHs) are pollutants that have attracted great attention in recent years regarding the issue of atmospheric pollution. Being harmful to human health, PAHs also promote the growth of secondary particles. Consequently, several countries have begun to control the emission of PAHs in exhaust gases with different techniques, which is a hot topic in the atmospheric environment field. Adsorption is one of the most significant methods and has been accepted by industries, of which the adsorbent properties are key factors. Researchers have studied the adsorption equilibrium, kinetics, and desorption properties of PAHs as special low-volatile gases on conventional activated carbons and novel mesoporous adsorbents. They have also examined the optimal balance between adsorption and desorption based on the corresponding adsorbents. In this paper, these results and related applications are reviewed, and the advantages of mesoporous adsorbents over traditional adsorbents on purifying PAHs are specifically analyzed. This work can be a reference for future studies on the adsorption purification of PAHs and other low-volatile gases.
